Overview
CG-2000 Master Clock Multi-Output Precision Generator
Supports redundant power sources, video/audio clock The best in the CG series, equipped with the functions required by broadcasting stations and postproduction sites
Features
- Two power supply circuits for redundancy [CG-2000 only]
- Supports video reference/word clock redundancy [CG-2000 only]
- Internal clock uses a high-precision OCXO (oven-controlled crystal oscillator) that is not influenced by the temperature of the environment
- External input connector that supports 10MHz, allowing creation of systems with even higher precision
- Jitter management circuit provides stable clock
- Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery
- Numerous output connectors, including (12) word clock outputs, enabling the use in large-scale video/audio synchronization systems
- Supports input and output of a variety of video signal formats, including NTSC, PAL and HD Tri-level
- AES3 and AES11 signals can also be used for external master clock input sources
- Analyzer function that can measure output device termination
- Optimal levels can be provided to other devices by adjusting wordclock output levels
- Error status can be outputted using GPO parallel output, allowing the monitoring of error occurrence
- Self-calibration function using an external oscillator (Atomic/GPS 10MHz, GPS PPS)
*Use of the self-calibration function requires the use of a separate PPS-output 10MHz oscillator with a built-in GPS antenna. - Word clock performance up to 192 kHz
- 0.1% pull-up/down for 24F(Film) and 29.97F(NTSC), and 4% pull-up/down for 24F(Film) and 25F(PAL)
- Up to (4) system settings can be saved to buttons for recall, and saved settings can be imported and exported via USB
- Durable nut-coupling BNC connectors made by Amphenol
- Independent circuit boards for each connector prevents contact failures due to twisting
- Three-prong IEC power cable included
- Panel-lock switch can be used to prevent inadvertent changes to unit operation
- 128x64-pixel organic EL display with a wide viewing angle
- Firmware updates possible using the USB port
- EIA 1U rack mount size
- RoHS-compliant product
